Hey, im just having a problem with my computer. When I turn it on it will go through a couple of screens like its going to start up, but then it goes to a black screen with a blinking white cursor in the top left of the screen. Please help, I am not sure of what to do!
Place your Windows 7 DVD in and boot to the "System Recovery Options" screen and select "Startup Repair", this will
scan your computer in an attempt to find and fix any startup problems.
There's also the possibility of having to do this more than once.
Once you've been able to get back in to Windows, I would run a few malware/virus scans, using Spybot-Search & Destroy, MSE and Malwarebytes, running them 1 after the other of course, to make sure your machine is not infected.
